Chemistry Question on Chemical Reactions

Some reactions of amines are given. Which one is not correct ?

A

B

CH3CH2NH2+HNO2→CH3CH2OH+N2CH_3CH_2NH_2 + HNO_2 \to CH_3CH_2OH + N_2

C

CH3NH2+C6H5SO2Cl→CH3NHSO2C6H5CH_3NH_2+C_6H_5SO_2Cl \to CH_3NHSO_2C_6H_5

D

(CH3)2NH+NaNO2+HCl→(CH3)2N−N=O(CH_3)_2NH+NaNO_2+HCl\to(CH_3)_2N-N=O

Answer

Explanation

Solution

Aromatic tertiary amines undergo electrophilic substitution with nitrosonium ion at p-position of the phenyl ring to form green-coloured p-nitrosoamines.
